MMR can cause skin problems and ulcers if your immune system is compromised

About the author:&nbsp

The MMR vaccine can cause serious adverse reactions, researchers have admitted this week. The rubella (German measles) component of the jab increases the risk of infection from the rubella virus itself, and can cause serious skin inflammation and ulcers in anyone whose immune system is compromised.

The risk is highest among people with primary immunodeficiency diseases (PIDD), chronic genetic disorders that cause the immune system to malfunction.

Although the risk for people with compromised immune systems has been known, and is even included in the package inserts supplied with the vaccine, it was theoretical, say researchers from the Children’s Hospital of Philadelphia, who say they have uncovered “genuine evidence of harm.”

The researchers analysed the health profile of 14 people—four adults and 10 children—who suffered some form of a PIDD. Seven of them still had the rubella virus in their tissues, suggesting that their immune systems were too weak to get rid of the virus in the vaccine. The virus can damage skin cells and cause ulcers, and makes the person more susceptible to the actual rubella virus, the researchers say.

People with a poor immune system already have compromised T-cells—which are responsible for clearing viral infections—and the MMR makes the problem worse.
